Why can the same battery push different amounts of current through different paths? Think about water in a hose. Pressure is the push, like voltage. Water flow is like current. A narrow hose restricts flow, like higher resistance. Voltage pushes charge, current is the flow of charge, and resistance opposes that flow. Ohm's law links all three: V equals I times R. Rearranged, current equals voltage divided by resistance. Here's the turn: the battery alone does not determine current. Resistance controls how much current a given voltage can drive. Keep the voltage the same, and increase resistance: current goes down. Reduce resistance, and current goes up. So why does one component draw more current than another from the same battery? Because current equals voltage divided by resistance. The same push creates more flow through the lower-resistance path-just as water moves more easily through a wider hose.
